What is CVE-2025-29824?
CVE-2025-29824 is a significant security vulnerability in the Windows Common Log File System Driver, which is a crucial component of the Windows operating system designed to manage logging functions. This vulnerability arises from improper memory handling, specifically a "use after free" condition, which can allow an authorized attacker to elevate their privileges within the system. The successful exploitation of this vulnerability could lead to unauthorized control over sensitive system functions and data, thereby posing substantial risks to organizations relying on Windows for their operations.
Technical Details
CVE-2025-29824 involves a critical flaw in the memory management of the Windows Common Log File System Driver. The specific vulnerability is categorized as a "use after free" issue, which occurs when a program continues to use a reference to memory after it has been freed. This type of vulnerability can lead to unpredictable behavior, including potential access to restricted areas of the operating system or the execution of arbitrary code with elevated privileges. The vulnerability requires local access to the system for exploitation, meaning that an attacker must first gain some level of access to the affected machine.
Potential impact of CVE-2025-29824
-
Unauthorized Access: Exploiting this vulnerability could allow an attacker to gain elevated privileges, enabling them to perform unauthorized actions that are typically restricted to higher privilege levels, including administrative functions.
-
System Compromise: Successful exploitation may result in the compromise of the entire system, allowing the attacker to install malware, exfiltrate sensitive data, or modify system configurations, leading to further security incidents.
-
Increased Risk of Data Breaches: With elevated privileges, an attacker could access sensitive information, posing a significant risk to data confidentiality and integrity. This could lead to severe data breaches, regulatory penalties, and reputational damage for affected organizations.
